GETTING STARTED
SETTING UP THE CLOCK
Insert batteries before rst use, matching the polarity (+
and -). RESET after each battery change.
SENSOR DATA TRANSMISSION
indicates main unit batteries are low.
NOT E Do not u se rech arge able ba tteri es. We
recommend that you use alkaline batteries with this product
for longer usage and lit hium batteries in tempe ratures
below freezing.
REMOTE SENSOR
The sensor collects temperature readings approx. every
40 seconds and sends them to the main unit. The main
unit can collect data from up to 3 sensors.
To set up the sensor:
1. Remove the screws from the battery door.
2. Insert the batteries, matching the polarity (+ / -).
3. Select a channel. Make sure you use a different channel
for each sensor.
4. Place the sensor near the main unit. Press RESET on
the sensor.
5. Simultaneously press CHANNEL and MEM on the main
unit to initiate signal sending between the sensor and
main unit.
6. Close the battery door and secure the screws
7. Place the sensor in the desired location using the table
stand or wall mount.
For best results:
• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 30 m (100 ft) from
the main (indoor) unit.
• Position the sensor so that it faces the main (indoor)
unit, minimizing obstructions such as doors, walls, and
furniture.
• Place the sensor in a location with a clear view to the
sky, away from metallic or electronic objects.
• Position the sensor close to the main unit during cold
winter months as below-freezing temperatu res may
affect battery performance and signal transmission.
Data is sent from the sensor(s) every 40 seconds. The
sensor reception icon in the remote sensor area shows
the status.

The sensor cannot be found.
Search for the sensor or check
batteries
To search for a sensor:
Simultaneously, press and hold MEM and CHANNEL for
2 seconds.
NOTE If the sensor is still not found, check the batteries,
obstructions, and remote unit location.
CLOCK
CLOCK RECEPTION
This product is designed to synchronize its date and time
automatically once it is within range of the WWVB-60 signal
from the atomic clock in Boulder, Colorado.
The sensor collects the radio signals whenever it is within
1500 km (932 miles) of a signal.
NOTE Initial reception takes 2-10 minutes for rst set up
or when RESET is pressed. Once complete, the reception
icon will stop blinking. If the signal is weak, it can take up
to 24 hours to get a valid signal.
RECEPTION SIGNAL
To enable and force a signal search:
Press and hold for 2 seconds.
To disable the signal reception:
Press and hold for 2 seconds.

The transmission range may vary depending on ma ny
factors. You may need to experiment with various locations
to get the best results.
Standard Alkaline batteries contain signicant amounts of
water. Because of this they will freeze in low temperatures
of appr oximat ely -12°C (1 0°F). Disp osable Li thium
batteries have a much lower threshold for temperature
with an estimated freezing range of below -30°C (-22°F).
Wireless ranges can be impacted by a variety of factors
such as extremely cold temperatures. Extreme cold may
temporarily reduce the effective range between the sensor
and the base station. If the unit's performance fails due to
low temperature, the unit will resume proper functioning
as the temperature rises to within the normal temperature
range (i.e. no permanent damage will occur to the unit due
to low temperatures).
